Unix Design Philosophy

We learned the basic Bash built-ins and GNU utilities to operate the file system. Now, we know how to run a program or copy a file using the shell. We can do the same things in a GUI. Both types of interfaces are effective for solving such simple tasks.

Bash provides several features that a GUI doesn’t. These features give us a significant performance gain when solving specific tasks. They can help automate our work and save time.

The following are the Bash features we are discussing:

1. I/O redirection.
2. Pipelines.
3. Logical operators.
